11 claims. (c1. 24-1z3) Myl present invention relates' to clasps forbracelets, and has particular reference to the construction of claspsfor Wrist watch straps of the cord type.

It has been found desirable to provide simple catch mechanism for cordbracelets, which may be quickly fastened and unfastened, and which willlock securely. To this end, I have devised a catch construction whichreceives a loop formed in one section of a cord bracelet, and I haveprovided means for locking the loop in received position. I have furtherprovided a simple means for adjusting the length of the cord bracelet tot the Vwrist of the wearer. 15 n With the above and other objects andadvantageous features in view, I have devised a novel clasp constructionmore fully disclosed in the detailed descriptionfollowing, inconjunction with the accompanying drawing, and more specifically definedin the claims appended hereto.v

In the drawing, v

v Fig. 10 is an enlarged perspective view of same, and

the cord holding elements.

Referring to the drawing, the wrist watch is equipped with a cordbracelet 16 having two portions 17, 18 secured'to the wrist watch by endhooks 19, 20, the two portions being releasably secured together by .aclasp member 21. The clasp member 21 includes a base 22 having a rearcompartment 23 to receive the two ends of the bracelet portion 17, thewalls of the compartment having aligned openings adjacent therearthereof to receive the pint-les 24 of the bent over end 25 of a lockplate 26, the edge of the end 25 having teeth 27 to detachably grip thetwo ends of the bracelet portion when the lock'plate is moved to thelocking position; the end 25 is Fig; 11 is a horizontal section thereof,showing' slightly out of perpendicular to the body of the lock plate, toproduce a binding effect when the lock plate is so moved.

A retaining tongue 28 is positioned at the front y of the base'22`, toreceive the loop 29 of the brace- 60 let portion 18, which is formed asa closed cord;

a cover plate 30 is hinged to the walls of the -1 compartment 23, inrear of the lock plate 26, and has fingers 31 to resiliently anddetachably engage the en'd of the retaining tongue.

The cover plate -is provided with a nail piece 32 to facilitatedisengagement from the retaining tongue. The bracelet portions 17 and 18have .the usual holding bands 33 of standard construction. p

The above described construction forms an effective clasp for the watchbracelet portions, and provides a cover part -that readily lends itselfto ornamentation. The length of the bracelet is quickly adjusted bylifting up the lock plate, and a further safeguard against accidentalunclasping is obtained by moving the band 33 towards the loop 29. i

4 The cover may be dispensed with, if the clasp is formed so as topermit locking of the loop'29. 80 Thus, .see Fig. 5, the clasp 34 has abase 35 with a rear compartment 36 and lock plate 37, similarv to thecompartment 23 and lock plate 26; a lock button 38 is positioned at theforward end of the base, the shank 39 being slender to prevent un- 85due spreading of the loop 29. A novel lock band 40 is provided to slideover the cords of the bracelet portion 18, see Fig. 6, consisting of ashell or case 41 which has its upper portion spaced to hingedly receivea ratchet plate 42, equipped with teeth 43 extending inone direction.The lock band is thus slidable towards theloop 29, but is locked againstbackward movement until the plate 42 is lifted; the end 44 of the plate42 is formed to resilientl-y contact the case when the plate is in lockposition.

The clasp may, if desired, be formed in one piece of metal, composition,wood, or the like, as shown in Fig. 9. In this form, the clasp 45'has arear retainer block 46 provided with spaced openings 47 to receive'thetwo ends of theA bracelet portion 17, these ends being tied after lengthp adjustment of the bracelet. The retaining button 49 is shaped as shownin Fig. 10, to better receive the loop 29 in locking relation; therearwardly pointed'end 50 leaves so little room between the button andblock that the loop 29 is substantially locked against accidentalremoval, as the fairly tight t of the bracelet will prevent, theunlocking backward movement of the loop;

. to safeguard the lock.

While I have described specic constructional forms of my invention, itis obvious that desired changes in the form and shape of the parts, andin their relation, may be made, without departing from the spirit andthe scope of the invention as defined in the/appended claims.
